155℃ Green Polyester Silicone Tape High Temp Masking for PCB Soldering

Produt overview

The 155℃ Green Polyester Silicone Tape is a specialized high-temperature masking solution engineered for precision applications in the electronics manufacturing and industrial finishing sectors. Constructed with a vibrant green PET film backing and coated with a high-performance silicone adhesive, this tape delivers exceptional thermal stability with a continuous operating temperature rating of 155℃. The distinctive green color provides enhanced visual identification on production lines, allowing operators to quickly verify mask placement on PCB gold fingers, edge connectors, and keep-out zones prior to wave soldering or conformal coating. With a dielectric breakdown voltage exceeding 5kV, it offers reliable electrical insulation alongside its masking function. The tape removes cleanly after thermal cycling, leaving zero adhesive residue on FR4, copper, steel, or aluminum substrates. Designed for PCB assembly technicians, powder coating applicators, and electroplating specialists, this green polyester tape ensures sharp masking lines and consistent performance in high-volume manufacturing environments.

Key Features

High Visibility Green Color: The vibrant green backing provides excellent contrast against PCB substrates and metal surfaces, enabling fast visual inspection and reducing masking errors on busy production lines.

155℃ Continuous Temperature Resistance: Maintains adhesion and dimensional stability during lead-free wave soldering, powder coating oven cycles, and paint baking processes without shrinkage or edge lifting.

Clean, Residue-Free Removal: Premium silicone adhesive system peels away smoothly after heat exposure, leaving zero sticky residue on sensitive electronic components, gold contacts, or coated surfaces.

Superior Electrical Insulation: Dielectric breakdown voltage exceeds 5kV, providing dependable protection for circuitry and connectors during soldering and high-potential testing operations.

Excellent Chemical Resistance: Withstands exposure to flux, solvents, and mild chemical baths commonly encountered in PCB assembly, electroplating, and industrial coating environments.

Conformable with High Elongation: Elongation exceeds 40% , allowing the tape to conform to irregular shapes, contours, and raised components while maintaining a secure edge seal.

Primary Applications

PCB Wave Soldering Masking: Protects gold finger contacts, edge connectors, and test points from solder splash and flux contamination during high-temperature lead-free wave soldering processes.

Solder Dip & Selective Soldering Protection: Masks designated keep-out areas on PCB assemblies undergoing selective solder dip operations.

Conformal Coating Masking: Creates sharp, defined boundaries for acrylic, silicone, and urethane conformal coatings applied after SMT assembly.

Powder Coating Curing Ovens: Masks threaded holes, grounding studs, and bearing surfaces that must remain coating-free during 150℃–155℃ bake cycles.

Electroplating & Anodizing Masking: Resists chemical attack in acidic and alkaline baths while providing clean peel-away removal after selective surface treatment.

Automotive Paint Baking: Suitable for masking trim pieces and creating two-tone paint lines during high-heat refinishing cycles in body shops.

Temporary Identification & Color Coding: The green color serves as a visual indicator for quality control stations, process tracking, or distinguishing between production batches.

FAQ

Q: Why should I choose green PET tape instead of transparent or amber?
A: The green color provides superior visual contrast against PCBs and metal parts. This allows production line operators to quickly verify proper mask placement and reduces the risk of missed or misaligned masking, improving overall throughput and quality control.

Q: Is this tape suitable for lead-free wave soldering temperatures?
A: Yes. The tape is rated for continuous use at 155℃ , which aligns with the preheat and solder wave temperatures typical of lead-free assembly processes. The silicone adhesive maintains its bond without charring or excessive shrinkage.

Q: Can this tape be used in automated tape dispensing equipment?
A: Yes. The consistent thickness and controlled unwind properties make it compatible with most automatic tape dispensers and laminating systems used in high-volume PCB assembly.

Q: What is the recommended storage condition and shelf life?
A: Store in original packaging at 23℃ (73℉) and 65% relative humidity. Under these conditions, the tape maintains optimal performance for 6 months from date of shipment.

Q: Can this tape withstand flux and cleaning solvents?
A: Yes. The PET backing and silicone adhesive exhibit excellent resistance to common PCB fluxes, isopropyl alcohol, and mild solvent cleaners used in electronics manufacturing.
